Image Forming Apparatus Error Identification Through Timing Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses face difficulties in determining the exact step or part causing an abnormality, leading to inefficient and labor-intensive part replacement processes, especially when the abnormality is not associated with a count value or involves multiple potential candidates.
Innovation Solution
An information processing apparatus communicates with an image forming apparatus to identify the error part by analyzing timing information related to errors in multiple components, such as a motor and loads, using a control unit to determine the error part based on first and second timing information stored in a memory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If parts are sequentially replaced and tested to identify the error part, then the error part can be identified, but the amount of work and time required increases significantly
Solution Approach 1:
The system performs preliminary actions by collecting and storing timing information from multiple sensors before an error occurs. This advance data collection enables rapid error part identification when an error happens, eliminating the need for sequential part replacement and testing.
Solution Approach 2:
The system implements feedback by continuously monitoring timing information from various components and comparing it against expected values. When an error occurs, the feedback mechanism uses stored timing data to automatically identify the error part, replacing the manual trial-and-error replacement process.
2Adaptability or versatility
If a failure notifying apparatus is associated with multiple parts, then more parts can be monitored, but it becomes difficult to determine which specific part requires replacement
Solution Approach 1:
The system segments the monitoring function by assigning dedicated timing information to each specific part. Instead of a single failure apparatus monitoring multiple parts, each part has its own timing data, allowing precise identification of which specific part failed even when multiple parts are monitored simultaneously.
Solution Approach 2:
The system adds a time dimension to part monitoring by collecting timing information from each component. This temporal dimension allows the system to distinguish between multiple parts not just by their identity but by when they operated, enabling precise error part identification in multi-part systems.
3Productivity
If count values are used to identify parts requiring replacement, then regularly-consumed parts can be tracked, but parts not associated with count values cannot be identified
Solution Approach 1:
The system changes the monitoring parameter from count values to timing information. Instead of tracking how many times a part has been used, the system records when each part operated, allowing the same monitoring approach to work for both regularly-consumed parts and other components that don't have straightforward usage counts.
